Will white Millennials become more Republican when they're middle aged?

[Sumner 1868]

More Republican than now obviously, but it won't be anywhere near the extent that the "you get more right-wing as you age" people seem to think (Fun fact: Obama won the 85+ vote in 2012, because those people were the Democratic GIs).

Eisenhower both times  , Nixon in 72 and Reagan both times I believe won the GI vote

It's difficult to say if Eisenhower won the GI vote or not in 1952, because the youngest ones were still in the under-30 category that year. He clearly did win a majority in 1956 though.

Didn’t the GI, Silent, Boomer, and Xer generations all get more Republican as they aged into middle aged adults and later into their elderly years?

Only Silents really became more Republican with age, and when you consider their midage was the counterculture, the Vietnam War, the Carter disaster, and then the Reagan credit boom, it's no wonder they became more Republican. They got even more so under Obama for both obvious and forgotten reasons.

GI's stayed about the same except in landslides, Boomers have always been intensely divided between the parties, and Xers have a big split because those who came to age under Reagan and those who did under Clinton.

[Sumner 1868]

If we use 1996 and 2008 as proof of "Republican aging," then we would have to say that 1984 is proof that the youngest Boomers and first-wave Gen Xers became more Democratic as they entered middle age.
